Valency is the combining capacity of an atom with another atom (s) .

This is normally given by the number of Valence electrons or by 8 minus the Valence electrons (Only when the number of Valence electrons is more than 4) .

Nitrogen is found to have either 3 or 5 valence electrons and lies at the top of Group 15 on the periodic table. It can have either 3 or 5 valence electrons because it can bond in the outer 2p and 2s orbitals.

➡Valence Electrons: 2, 5

➡Electron Configuration: 1s2 2s2 2p3

➡Name and Symbol: Nitrogen, N

➡Group: 15

Valency......

The measurement of the power of an atom to combines with others

The valency of Nitrogen

N

Having mass = 14

Atomic number = 7

K L M N

2 5 0 0

Atomic no. - K =.... -L= valency

7-2 = 5-8 = - 3

Therefore, the valency of Nitrogen is - 3.

subodhkumar17095: but wrong this
Anonymous: but sir.... how..??
subodhkumar17095: your answer is correct but process is wrong
subodhkumar17095: now may check you N has 3 unpaired electron then valency is 3 or from octate rule you get it
